What's Covered

In this lesson, you’ll learn how to monitor the cost of a project.  Specifically you will focus on:

  1. Monitoring Budget
  2. Monitoring Tasks
  3. Reporting Time, Effort and Percent Complete


Like schedules, the project manager is responsible for monitoring the budget on a project and tracking the actual cost spent versus the original cost estimates.

A project manager tracks all elements in a project that result in costs to the project. This includes effort needed to complete tasks, materials used to create deliverables, and services that are used as part of the project budget, such as subscriptions to development software.  When a task has been completed, the project manager compares all of these costs to complete the task to the original estimate and records if the task was over or under budget. If additional budget is required, then the project manager must seek approval from the project sponsor and key stakeholders.

Term to Know

Budget Monitoring
The ongoing tracking of the estimated budget compared to actuals.


How does a project manager estimate cost on a task that is still in progress? To do this, two values must be tracked.

  1. First, team members must continually report their effort in hours on tasks. This can occur on a daily or weekly basis.
  2. Second, team members must report the percent they have completed a task. This is often done on a daily basis, but for larger projects with longer tasks, sometimes weekly will work too.
  3. The project manager then takes these two values and uses them to calculate the amount spent on a task so far.

ExampleAssume that during the planning phase, the quality assurance on a mobile email application was estimated to take 40 hours to complete. The quality assurance task has now begun, and we want to know the cost spent. At the end of the week, the team reports that they have spent 20 hours on the task, and that it is 60% complete.

Remember that 40 hours is the original estimate to complete the task. We multiply 40 hours times 0.60 for the percent complete to arrive at 24 hours, which is how much effort should have been spent to reach 60% complete.

However, the team has only spent 20 hours. So we are four hours ahead of schedule. If the cost per hour of a team member is $30 per hour, and we are four hours ahead of schedule, then $30 times four hours equals $120 under budget for the task. Pretty good!


Most project management software tools will perform this calculation. So you won't have to do it manually. However, each organization will use different methods to record the effort on a project. Here's an example of a template for team members to use. 

Note that it shows the project tasks assigned to the team member and has a space for them to record their time or effort on the task and the percent the task is complete.  It will vary by organization how often team members provide these reports and how often the project manager will report on the budget. But the general process is the same.


In this lesson, you learned how a project manager monitors the budget, how to track the costs associated with the task, and how team members report on the effort, time, and percent complete for each task.

Good luck.
